Question

A swimmer swims 4 laps in 3 minutes. What is the swimmer’s unit rate..? Would you divide 4÷3?

Answer 1

The rate can be calculated below

$rate=\frac{\text{laps}}{\text{time}}=\frac{4}{3}\text{ laps per minutes}$

1 minutes = 60 seconds

3 minutes = 180 seconds

Therefore,

$\text{rate}=\frac{4}{180}=\frac{1}{45}\text{ laps per seconds}$
